PI3HDMI411AD DVI / HDMI Re-Driver w/ Equalization, De-emphasis & Pre-emphasis Features Description • • • • • • Pericom Semiconductor’s PI3HDMI411AD, active-drive switch solution is targeted for high-resolution video networks that are based on DVI/HDMI standards, and TMDS signal processing. The PI3HDMI411AD is an active single TMDS channel re-driver with Hi-Z outputs. The device drives differential signals with enhanced signal integrity to video display units. It provides three controllable output swing levels that can be controlled through pin control or I2C control, depending on the mode select pin. The swing levels are 500mV, 700mV, & 1000mV. This solution also provides a unique advanced pre-emphasis technique to increase rise and fall times which are reduced during transmission across long distances. • • • • • • • • Supply voltage, VDD = 3.3V ±5% Compatible with DVI, HDMI, rev 1.1, 1.2, and 1.3 signals Supports both AC-coupled and DC-coupled inputs 8-Bit, 10-Bit, and 12-Bit deep color support Configurable output swing control (500mV,750mV,1000mV) Configurable Pre-Emphasis levels (0dB, 1.5dB, 3.5dB, & 6.0dB) Configurable De-Emphasis (0dB, -1.5dB, -3.5dB, -6.0dB) Configurable Equalization (1dB, 3.5dB, 8dB, Optimized EQ) Data Rate = 2.5 Gbps (max) ESD protection = 6kV (Typical) Inputs w/ built-in termination per HDMI spec Propogation delay < 2ns input Uni-Directional Packaging (Pb-free & Green): 56-contact TQFN (ZB56) The maximum DVI/HDMI data rate of 2.5Gbps provides a 1920x1080 resolution required w/ 12 bit/channel color depth, by the next Gen HDTV and PC graphics products. PI3HDMI411AD is the industry’s first active DVI/HDMI compliant switch, which ensures transmitting high bandwidth video streams from PC graphics source to end display units. The Optimized Equalization provides the user a single optimal setting that can provide HDMI compliance for all cable lengths: 2meter, 10meter, 15meter, and 20 meter. Pericom also offers the ability to fine tune the equalization settings in situations where cable length is known.

If a DTV is designed with a side/front HDMI connector, a Separate daughter card is needed for the side/front HDMI connector and Pericom re-driver. ATC compliance MUST only be maintained from the front/side connector to the PI3HDMI411AD IC. After the PI3HDMI411AD signal Integrity will be taken care of through the powerful pre-emphasis technique of the Pericom solution.
